JB3 PNP PRoblem! HELP!

So last night i installed my jb3 pnp and when i reconnected the batery etc. and started the car i got a "Engine Malfuction" "Transmiission problem" along with "REDUCED acceleration" on my navi. i cant go anywhere on my navigation its just stuck....

also while driving on the freeway i floored it to see how it would pull, this put the car in limp mode i guess because i had nooo power. just restarted the car but it happened again. :/

i dont know whats wrong maybe someone could help. its dosnt feel much faster, dosnt loose traction either. maybe installed wrong?

I dont have a JB3 but, this sounds like the problem. Why not check to see if you put the right cables in the right slots? Double check the connectors. Make sure everything is making contact properly.

if that doesn't work uninstall the JB3 and start the car see if the warning comes up again.. If it doesn't try to reinstall it more carefully.

double check the connections per the bms installation instructions. Start with map zero, and then work your way up depending on your modifications.

This might sound crazy, but instead of making threads why don't you contact BMS for tech support. Terenceburger@gmail.com

+1,000 contact Terry, he's surprisingly quick at answering his emails, especially if it's tech/install support!

So when you started the car and got a CEL, what possessed you to go drive around? Check the troubleshooting section in the JB3 PnP section install guide, and if you can't figure it out contact BMS for technical support.
